New experiences showed that the essence of Mars is much faster than the Earth’s heart, thanks to the molten iron and nickel sulfids that leak through solid rocks and in the middle of the red planet.
Planets We are layerTo some extent, it is like onions. The surface on which we stand is cortexWho sits over a cloak. We find a solid external heart and a molten internal nucleus, spinning can generate a global magnetic field.
Planetary scientists call this layer “differentiation”, meaning that the different elements were able to distinguish between each other. The heaviest elements, especially iron and nickel, are usually drowned in the hearts of the planets, while the elements of silications remain lighter in the outer layers. However, scientists usually assumed that in order for iron and nickel to drown in the heart of a planet, the inner design of the planet must be, first melting in the heat that its chest Radiant decay From aluminum 26 and perhaps iron 56.
This is definitely how landJawhar was formed, at least, in a process of scientists estimated at one billion years or more. but Mars It displays a luster in this story. Mars Meteorites It contains radiant appetite evidence sensitive to forming the heart Solar power system. It seems that the effects of this are that Mars has grown much more quickly than Earth, but the formation of the solar system formation has struggled to repeat this.
Now, scientists in the Department of Research and Exploration Sciences believe at the NASA Johnson Research and Exploration Center. Perhaps they discovered how Mars could be its essence so quickly without trying any abnormal growth mutations early.
About 4.5 billion to 4.6 billion years ago, the planets moved from a gas and dust disk that cordoned off sunAnd called a protoplanetary. The infant’s gravity pulled the heaviest elements and minerals, including iron and nickel, to the inner campus of the disk. Meanwhile, lighter materials such as water and hydrogen resided in the outer parts of the disk.
The place where Mars was sitting somewhere between those sections. There is still a lot of iron and nickel in the vicinity, but there was also room for lighter elements such as oxygen and sulfur. The team in Ares realized that this could have had an impact on how to form the essence of Mars, so they took the test. By doing this, they produced the first direct evidence that iron sulfids and molten nickels can leak through small cracks between minerals in a solid rock, and ultimately accumulate in the heart of the planet after only a few million, long before the shift of radioactive decay to the internal molten.

The scientists, under the leadership of Sam Krosli, who has since moved from Ares to Arizona University in Tuxon, conducted high temperature experiments at the NASA Johnson Experimental Petroleum Laboratory Laboratory, where samples of sulfate-rich rocks are heated that exceed 1020 degrees Celsius, which are hot enough to dissolve sulfids-is not a rock rock. They then investigated the hot samples at the X -ray Central Photography Laboratory in the space center to see if the sulfide has declined through solid rocks.
Crossley said in a statement.
Everything is good and good to show this in the conditions under the censorship inside the laboratory, but can it actually happen in the gut of a planetary body? Certainly, the team must double the verification of their hypothesis against the materials that were once part of the planetary body.
“We took the next step and searched for criminal chemical evidence to nominate sulfide in meteorites,” said Crossley. “By partially melting artificial sulfide with the trace minerals of the platinum group, we were able to reproduce the same unusual chemical patterns found in oxygen -rich meteorites, providing strong evidence that sulfide filtration occurred in those conditions in the early solar system.”
However, the identification of this platinum trace group minerals, specifically Iridium, Osmium, palladium, platinum and routinium, without destroying samples requires some smart technologies created by Ares Jake Cityra researcher.
“To confirm what the 3D perceptions show, we needed to develop the appropriate laser detection method that could follow the elements of the platinum group in these complex experimental samples,” Cetira said in the statement.
The Sterera method found that molten sulfide passage through the left left rock residue of these platinum minerals in samples in quantities that correspond to those in cartilage meteorites.

“Our hypothesis has confirmed – that in a planetary environment, this heavy melting will migrate to the center of the body and form a heart, even before the rock around the melting begins.”
This model of the basic composition applies to all the important important bodies residing in that central region of the protoplantite disk, not only Mars. However, given the mystery of Mars formation, the results that are likely to answer some basic questions about the first days of the red planet, and make the prediction that the heart of Mars should be rich in sulfur. And you know how the sulfur smell is? Correct eggs.
The research was published on April 4 in the magazine Nature Communications.
